IMPRO-VEMENT IN ATTACHING DlClNG-STONES T0 WHEELS vFOR POLIS'HINGLEATHER.

The Schedule, referred to in these Letters Patent and making parl: ofthe same.

art to make and use the same, reference being had to the accompanyingdrawing forming part of this speci iication.

Figure l represents an end view of a stone secured vaccording to ourimproved method.

Figure 2 is a plan'view of the same.

Similar letters of' reference indicate corresponding parts.

This invention relates to a new method of securing stones or equivalentgrinding or scouring articles to the rims ot' wheels or cylinders, withan object of insuring-a simple method otfastening said stones, and ofsecurely retaining the same in place.

Our invention consists in providing metal troughs, which are bolted tothe rim vof the cylinder or wheel, and receive the stone, imbedded insulphur.

A in the drawing represents the'stone vtobe secured.

B is a metal trough, enl. rged toward its hase, and ot such suitablelength and wid-th as to receive the stone .to about half its height.

A bolt or bolts, G, projecting through thebotton ofthe trough, serve tosecure the same to the rim D of the wheel or cylinder.

lVhile the stone is being imbedded inthe trough, molten sulphur. ispoured into the same, to constitute a binding substance, a, around theimbedded portion ofthe stone, as shown. rlhe lower part of the stone mayhe grooved or roughened, to give a firm hold to the sulphur. Instead ot'sulphur, equivalent substance may be employed.

Our invention refers more particularly to the employment of the trough.-Stones were heretofore titted into dovetail or other grooves ot' thecylinder, or otherwise directly fastened thereto, preventing a Vfirmimbedding. It a stone was worn, it had to be replaced in the shop, whereit could not be properly bedded.

By the use of our trough the stones can be conveyed,

1to. order, properly imbedded, to any desired place, and are thenreadily fastened by means of the bolts. Stones thus lsecured may in'suitable numbers be readily fastened to cylindrical or other surfaces.

Having thus described oui-invention,

Ve claim as new and desire to secure hy Let-ters Patent- A.

The trough B, constructed to receive the imbedded stone A, and the boltor bolts C, by which-said stone is secured to a cylindrical or othersurface, substan tially as herein shown and described. v
